Te allwiem @man 00a/0.6m" 1 Be it known. that l., Heier NICHOLS, a citizen of the United States, residing at Rupert, in the county-'of Minidoka and State of Idaho, have invented certain new and useful Improvements in Manifold Heaters', of which the. following isa specification.

rlhis invention relates to `iInprovements in manifold; heaters for internal combustion engines'.

An important object of the invention is the provision of a. manifold' heater. which will heat the intake manifold, in suchy manner, as to. effQClfVely vapori-ze gasoline prior to its entry into the cylinders of the motor. LA. further 'object ofthe invention `is...the provision of a manifold heater includingv an auxiliary heatingqdevicefor heating the in; take manifold in cold weather, in such manner` that a low gradeof gasoline canreadily be. vapcrized..

A further object of thevinvention :is the prov.isionv` of a manifold heating device, which incloses the intake pipe, and; thus pre vents cooling effect of the fan, thereby aiding the vaporization ofthe gas therein, in such manner, as tofproduce regular eXp-losions in the cylinders, thus ypreventing-vibration 0f the engine Other advantages will be apparent duri ing the course ofy the following ydetailed description. l u inthe accompanying drawings forming a part of this specification and in which like reference characters designate like aparts throughout the same, l vFigure-l is. a side elevation of a Ford internal combustion engine having the: improved manifold hea-ter attached thereto.

Figure 2 is an enlarged front elevation of the manifold heater. n

Fig. 3 is a front elevation showing the casing of the manifold heater with the cover removed.

Fig. 4 is a horizontal cross sectional plan view taken through the manifold heater. Fig. 5 is a vertical cross sectional view through the manifold heater showing the ar-v rangement of parts therein. Fig 6 is a perspective view of the auX- iliary heating element embodied in the mani-Vv fold heater. y

In the drawings whereink for the purpose of illustration is shown a preferred embodiment of my invention the letter A designates an internal combustion engine of thel Specicaton of Letters Patent.r

1 The manfold'heater .D comprises. a Casing 1,0.' having apertures ll and l2 in the back. thereof adapted to t over the. two center glands of the exhaust manifold; and having apertures 1.3 and 1 4 in the back thereof, provided to fit over the two `vglands ef the intake manifeldvThe face 0r front ef the. Casingl is. preferably open. The.

uinani-foldj heaterI Dis preferably maintained `(i0 brackets .16 are positioned upon the floor li' u regula-,te the area vof opening of; the yaperture Qlfcominunicating with theinterior of the manifold heater-G- A knob 25 is carriedI` bythe doors to, facilitate swinging upon their pivot 24u, and. it is to benoted in this connection Vthat the. f rictional contact'` ofthe doors 22 and .23.with theface of the cover 1,8 is suiiicient tohold thedoors v22y and 23 in an adjusted position.

. The. burners` G comprise metallic box portion 26 iilled with asbestos wool27 and covered by wire gauze 28. The asbestos wool is adapted to be saturated with denatured alcohol, or gasoline for the' purpose of ignitingthe same to provide an auxiliary heater.

' In order to attach the improved manifold heater to an internal combustion engine, remove the exhaust and intakemanifolds, by removing the clamps The casing v10 is then slipped over the glands of the exhaust and intake manifolds in such manner that the two center glands of the exhaust manifold are positioned within the apertures 11 and l2 of the casing, and the two end glands of the intake manifold are positioned within the apertures 13 and 14 in the casing 10. It

lll

isto be noted that the bolts of the glands E are inserted through apertures 30 in the back of the casing 10. The lid 18 is then placed upon the casing 10, in a position that the apertures 2O and 21 are directly in front of the burners G, and in such manner, that apertures 31 therein receive the bolts of clamp E. The clamp members E are then tightened upon the lid 18 until the same is firmly positioned upon the casing 10.

Ordinarily the heat from the exhaust manifold is suflicient to heat the intake manifold in the interior of the manifold heater, and in such manner that the device Will function properly.

However, if the Weather is severely cold the auxiliary heaters G are ignited through the apertures 20 and 21, and the doors 22 and 23 positioned in such manner that suilicient oxygen Will reach the burners as to permit operation. Since all parts of the manifold heater D are protecte-d from the currents of air from the fan F', the device could be used upon an automobile, and the burners would still function correctly.

It is to be understood that the form of my invention herein shown and described is to be taken as the preferred example of the same, and that various changes in the shape size, and arrangement of parts may be resorted to Without departing from the spirit of the invention and scope of the sub-joined claims.

I claim: l

1. In a manifold heater, the combination, With an internal combustion e-ngine having exhaust and intake manifolds, of a casing enclosing said intake manifold and a portion of the exhaust manifold, auxiliary burners positioned Within the casing for heating the intake manifold, a detachable lid for the front of said casing to permit access to the burners, said lid having apertures therein adjacent the detachable burners, and adjustable doors mounted upon said lid for regulation of the opening into said casing.

inname with a Ford7 internal combustion engine, having exhaust and .intake manifolds, and clamps therefor, of, a casing having apertures therein to fit over the glands of said manifolds in order to position the manifolds inside thereof, said casing maintained in position upon said Ford engine by the manifold clamps.`

3. In a manifold heater, the combination, with a Ford internal combustion engine, having exhaust and intake manifolds, and clamps therefor, of a casing having apertures therein to fit over the glands of said manifolds in order to position the manifolds inside thereof, and a detatchable lid for the face thereof, said lid and casin being maintained in position upon said ord engine by the manifold clamps, and doors pivotally mounted upon said lid whereby access may be had to the interior of the casing.

4L, In a manifold heater, the combination, with a Ford internal combustion engine, having exhaust and intake manifolds, and

clamps therefor, of a casing having apertures therein to fit over the glands of said manifolds in order to position the manifolds inside thereof to protect the same from cooling effect of the fan, and detachable burners positioned Within said casing, said casin i being maintained in position upon said Ford engine by the manifold clamps.

5. In a manifold heater, the combination with a Ford internal combustion engine including exhaust and intake manifolds and a clamp therefor, of a casing including a rectangular shaped body portion for disposition to entirely receive the intake manifold and a portion of the exhaust manifold, said body portion having apertures therein adapted to fit over the glands of said mani` folds, detachable burners positioned in said body portion upon both sides of said intake manifold, and therebeneath, and a detachable lid for disposition upon said rectangular body casing to entirely enclose the intake manifold and a portion of the exhaust manifold therein.
